A football team has a net yardage of −28 1/3
yards on a series of plays. The team needs a net yardage of 30 yards to get a first down. How many yards do they have to get on their next play to get a first down?
Answer: 58 1/3 yards
Step-by-step explanation:
From the question, we are informed that a football team has a net yardage of −28 1/3 yards on a series of plays and that the team needs a net yardage of 30 yards to get a first down.
The number of yards that they have to get on their next play to get a first down would be calculated as:
= 30 - -28 1/3
Note that minus × minus = plus
= 30 + 28 1/3
= 58 1/3 yards
How do you know if a point is a solution to a linear inequality
Answer:
To see if an ordered pair is a solution to an inequality, plug it into the inequality and simplify. If you get a true statement, then the ordered pair is a solution to the inequality. If you get a false statement, then the ordered pair is not a solution.

the slope of the line that passes through the points (2,3) and (5,9) is
Answer:
The slope is 6/3 or simplified is 2
Step-by-step explanation:
Stick to this formula
y2-y1/
x2-x1
9-3/
5-2 = 6/3 or 2
See attachment for further explanation
Hope this helps (:
The slope of the line that passes through (2, 3)(5, 9) is 2
Slope formula is describe below:m = y₂ - y₁ / x₂ - x₁Therefore, the slope of the line that passes through the points (2, 3)(5, 9) can be found as follows;
y₁ = 3
y₂ = 9
x₁ = 2
x₂ = 5
m = 9 - 3 / 5 - 2
m = 6 / 3
m = 2
slope = 2
Therefore, the slope of the line that passes through (2, 3)(5, 9) is 2

Use the associative property of addition to write an equivalent expression for (x+17) + y
An equivalent expression is
Answer:
x + (y + 17)
Step-by-step explanation:
The associative property of addition is characterized by altering the order of operations by putting brackets in a different place. The answer will always be the same. Just the order is different.
So one possibility and the one you are likely expected to give is
x + (y + 17)
That means that if 17 and y can be added by giving y a value, then they will be done first.
Then you add z to the result if it has been given a value.
The answer you are expected to give is x + (y + 17)

Answer:
111.46 units
Step-by-step explanation:
The right triangle has side lengths that are 1/√2 times the hypotenuse length, so each is (18√2)/(√2) = 18 units. The top is this length shorter than the bottom, so the total of all side lengths (CW from left) is ...
18 + (43 -18) +18√2 +43 = 86 +18√2 ≈ 111.46 units

Four families went out for lunch. The total food
bill came to $167. The families also left a $30 tip for the
waitress. If each family spent the same amount, about how
much did each family spend on dinner? Explain how you
found your answer.
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though

Tim goes on a car journey.
for the first 15 minutes his average speed is 40 mph
he then stops for 25 minutes
he then completes the journey at an average speed of 45mph
the total journey time is 1 hour.
A) draw a distance time graph for his journey?
B) what is the average speed for the whole journey?
Answer:
See attached picture ;
25 miles / hour
Step-by-step explanation:
First phase :
Travel time = 15 minutes
Average speed = 40 mph
Distance covered = speed * time
Distance covered = 40 * (15/60) = 10 miles
Second phase :
25 minutes stop
Third phase :
Average speed = 40 mph
Distance covered = speed * time
Travel time = 60 - (25 + 15) = 20 minutes
Distance covered = 45 * (20/60) = 15 miles
Average speed for the journey :
Total distance / total time taken
= (10 miles + 15 miles) / 1 hour
= 25 miles / hour

To find:
The number and types of solutions for the given equation.
Solution:
We have,
[tex]6m^2-3m-4=0[/tex]
It is a 2nd degree polynomial because the highest degree of the variable x is 2.
Number of solutions = Degree of the polynomial
Number of solutions = 2
Therefore, the given equation has 2 solutions.

[tex]D=b^2-4ac[/tex]
[tex]D=(-3)^2-4(6)(-4)[/tex]
[tex]D=9+96[/tex]
[tex]D=105>0[/tex]
Therefore, the given equation has two distinct real solutions.
Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats. Which equation gives an area A as a function of the width w of the enclosure?
A(w)=180−w2
A(w)=360−w2
A(w)=180w−w2
A(w)=360w−2w2
Answer:
A(w) = 180w-w²
Step-by-step explanation:
Farmer Brown has 360 feet of fencing to use to construct a rectangular enclosure for his prized goats.
It means that the perimeter of the rectangle is 360 feet
The formula for the perimeter of a rectangular shape is given by :
P = 2(l+w)
l is length and w is width
ATQ,
2(l+w) = 360
(l+w) =180
l = 180 -w .....(1)
The formula for the area of a rectangle is given by :
A = lw
Put the value of l form equation (1).
A = (180-w)w
A(w) = 180w-w²
Hence, the correct option is (c).
